At age 20 you invest $2900 that earns 11.75 percent each year. At age 30 you invest $2900 that earns $14.75 percent per year. In which case would you have more money at 60?
To calculate the future value we use the formula below
A = P (1 + r)^n
Where:
A = the future value of the investment including interest
P = the principal investment amount
r = the annual interest rate (decimal)
n = the number of times that interest is compounded
Someone who starts saving and investing in a disciplined manner at an early age gets the advantage of compounding whereby interest earned participate in future capital appreciation and longer the investment period, compounding works more in favour of achieving their financial goals.
Below example will explain you the power of compounding and the importance of starting early.

From the above, we can say that, if we invest at the age of 20 then we would you have more money at 60.
Working notes:
At age 20:
Amount (A) = 2900*(1+0.1175)^40
Amount (A) = $246774.
Wealth gained = $246774 – initial investment
Wealth gained = $246774 – $2900 = $243874.
At age 30:
Amount (A) = 2900*(1+0.1475)^30
Amount (A) = $179878
Wealth gained = $179878 – initial investment
Wealth gained = $179878 – $2900 = $176978.
